* Client logout processing is much better now ( still far from perfect ) :
- the logout timer appears as it should
- player entities are removed from the server ( newly connecting players won't see stale heroes hanging in mid-air )
- The entity delete messages are not sent yet ( so while logged in, the client might still see frozen heroes )

* Small fix to properly send orientation of perceived-entities, so everyone should be much more vertical now :)

in one suthe diyhele hale,
